DeWalt DC730KAR Hammerdrill Operation fi g, Screwdriver Operation fi g, Lubrication, Cleaning

ENGLISH

5.To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole.

6.Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming.

7.With variable speed drills there is no need to center punch the point to be drilled. Use a slow speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep enough to drill without the bit skipping out.

Hammerdrill Operation (fi g. 5)

1.Turn the collar (c) to the hammerdrill symbol.

2.Select the high speed setting by sliding the selector back (away from the chuck).

IMPORTANT: Use carbide-tipped or masonry bits only.

3.Drill with just enough force on the hammer to keep it from bouncing excessively or “rising” off the bit. Too much force will cause slower drilling speeds, overheating and lower drilling rate.

4.Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit when drillling as this will cause clogging of the bit flutes and a slower drilling speed.

5.When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the hole with tool stil running to help clear debris from the hole.

NOTE: A smooth, even flow of dust from the hole indicates proper drilling rate.

Screwdriver Operation (fi g. 6)

1.Select the desired speed/torque range using the dual range gear selector to match the speed and torque of the planned operation.

2.Turn the torque adjustment collar to the desired position. Lower numbers indicate lower torque settings; higher numbers indicate higher torque settings.

3.Insert the desired fastener accessory into the chuck as you would any drill bit.

4.Make some practice runs in scrap or on unseen areas to determine the proper position of the clutch collar.

5.Always start with lower torque settings, then advance to higher torque settings to avoid damage to the workpiece or fastener.
